Burst Mode Operation  
Discontinuous Conduction Mode (DCM),  
Dynamic SR On/Off Control with  
Programmable Threshold  
DESCRIPTION  
The UCC28950 enhanced phase-shifted controller  
builds upon Texas Instrument’s industry standard  
UCCx895 phase-shifted controller family with  
enhancements that offer best in class efficiency in  
today’s high performance power systems. The  
UCC28950 implements advanced control of the  
full-bridge along with active control of the  
synchronous rectifier output stage.  
–
Programmable Adaptive Delay  
•
Average or Peak Current Mode Control with  
Programmable Slope Compensation and  
Voltage Mode Control  
•
•
Closed Loop Soft Start and Enable Function  
Programmable Switching Frequency up to 1  
MHz with Bi-Directional Synchronization  
The primary-side signals allow programmable delays  
to ensure ZVS operation over wide-load current and  
input voltage range, while the load current naturally  
tunes the secondary-side synchronous rectifiers  
switching delays, maximizing overall system  
efficiency.  
•
(+/-3%) Cycle-by-Cycle Current Limit  
Protection with Hiccup Mode Support  
•
